Spin Wave Dispersion of the van der Waals Antiferromagnet NiPS${}_3$

Ritesh Das, Rob den Teuling, Artem V. Bondarenko +4

We calculate the magnon dispersion spectra of the two-dimensional zigzag van der Waals antiferromagnet NiPS${}_3$ for monolayer, bilayer, and bulk systems as a function of an externa…
